I Patented April 9. 1907.

To all whom it may concern:

Be it known that I, JosEPH A. RHoUL'r, a citizen of the United States, and a resident 'of Haverhill, in the county of Essen (and State of Massachusetts, have invented a new and Improved Shoe-Sewing. Machine, of

description.

The invention relates to a machine especially, designed forsewing shoes and other heavy-work and to be used in connection with the novel process for making shoes diswhich process the up ers of the shoes are sewed to the soles in t eir natural position,

The invention also involves variousii'morming the subject ofmy prior patent, No.

The object of my present invention is to simplify and otherwise improve the means for carrying the thread' It is also an object of my inventionto improve the stitch-forming devices and provide stitching operation and for releasing the sole during the feeding movement thereof.

A further object of the invention is to sim plify and render more certain of operation the devices for driving, the thread-carrier and stitch-forming elements; and still a further object is to adapt the machine to the work ofsewing felt or other fabric uppers gripping and feeding'the felt upper, as well as the sole.

Tothese ends my invention resides in certain novel features of construction and combinations of elements which will be fully set forth hereinafter and pointed out in the claims; i g l Reference is to be had to the accompanying drawings, which illustrate, as an example, one manner of practically embodying my invention, in which drawings like characters of reference indicate like parts in the several views, and in which- I Figure 1 is afront elevation'of the machine. Fig. 2 is a plan view of the same. Fi 3 is ig. 2, showing especially the needle-bar, cast-off,

The apparatus as here shown has a frame formed of a base 20, having side parts 21 rising therefrom and supporting a work-plate ortable 22. This wor late may, if desired,

.be provided with a 'stitc plate 23 let thereinto ,as the drawings show. Mounted on the side parts 21 of the frame'is a rotating'ishaft 24, constituting the prime mover of the machine and provided with a band-wheel 25, through the means of which the shaft maybe continuously rotated.

The shaft 24 is provided (see Figs. 3 and 6) with an eccentric 26, the str'apl27 whereof is received in the forked end 43 of the operatgaging the sole and feeding the same in a polever 42, having a rctractilc spring 46 in conowe joined. by a link 28 to a lever 29. This lever lies above the shaft 24 under the work-plate 22 and has its rear end l'ulcrumed on a lug 30, depending from the work-plate At its free i or forward end'th'e lever 2.) is joined to a link i Lw ich extends downwardlyand is pivoted to a bracket 32, fastened to the-needle-bar 33. The needleba'r extends vertically and is reoiprocally held in the base 20 and in a hanger 34 depending from the work-table 22. The needle-bar 33 carries at its upper end a noes tile 35, which has a hook, as shown, and is ada ted to move with the bar 2%.) back and fort 1 through the stitchlate 23. The upper portion of the needle-bar 33 has, a groove 3; therein (sec. Fig. 6) and in this groove playsthecast-oll'3h. 'lheelemcntsilfiand36, coacting with the thrmul-carricr to be hereafter described, form the usualchain-stitch, as will be understood from the prior art. The cast-oil'36 is attached to a slide 257, which operates vertically and lies in front of the neodle bar 3-3. Said slide is provided at its lower portion with a fork as, which [its in a guide 39, carried on the base 20. Said guide is provided with'a pin 40, which passes bctween the tines of the fork its to hold the slide 37 against lateral movcincnt.

41 indicates a leafspring which is at t achcd to the frame at its lower cnd and which has its free upper end pressing against the slide 37, thus holding the cast-oil 3t \'ieldingl in the groove 33 in the necdlc-bar 253. 'lhc slide 37 has a pin 42, (see the full lines in Fig. 1 and broken lines in Fig. 3,) and this pin is lug-lever 43. lhis lever 43 is intcrmcdiatcly fulcrurned on a pedestal -44, rising from the base 20, and extends rearward over a-cam 4:),' attached to the shaft 24, the rear end of the nection therewith, this spring holding the lever yicldinglv engaged with the cam. By the devices above described the needle and cast-oli are, mounted in )ropcr coact ive rcla-' tion and are coopcrat ivcly driven to form the stitch.

47 indicates the feed-dog \V-lilCltlittS a (zonihined reci rocating and vibratory movement through t in stitch-plate 23, periodically cnsit-ion to receive the next stitch. The feeddog is carried on the upper end of a lever 48, (see Fig. 5,) which has a combined vibratory and sliding movement permitted by a fulcrum-pin 49 passing through a slot 48" in and intermediate the ends of'the leverd At its 1 lower end the lever is bifurcated t receive a slide 50, which is adjustable longitudinally on vthe level; by means of a thumb-screw 51. To this slide is connected a floating lever 02. Said lever is pivoted to the slide and extends rearward over the base 20 and under the shaft 24, therear-eml of the lever being sac.

loosely fitted in an orifice 20 in the rear of the base, the arrangement bein such that the lever 52 isfree to slide aswe l as to rock slightly in said cavit 20*. A retractile spring 53 is joined to the front end of the lever 52 and extends upward under the work-plate 22, this spring 53 tending to lift the front end of the lever 52 and the parts 48 and 47 connected to the same. The lever 52 is also provided with a spring 54, which is joined to the lever and extends rearward alongside of the same into connection with the rear part of the base 20, this spring tending to nove the lever 52 rearward, and through said lever tending to rock the lever 48. 55 risingtherefronl in front of the shaft .24, and this stud isengaged by a cam .36, attached to the shaft. Engaging 'a track 52 on the lcvcr 52 is a cam 57, also attached to the shaft 24. Said cams and 57, acting with the parts 5.3 and 52, impart to t he lattcr element a combined rcciprocating and vibrating movement, the lcvcr 52 being returned fromeach movement, respectively, by the springs 53 and 54. This movcmcnt of the lever 52 in turn imparts to the lever 48 and fccddog 47 their charactcrist ic movement.

()pcrativc through the opening in the stitch-plate 23 is a forked work-locking dog (Sec Figs. 1, 3,7,and 8.) This locking dog is adapted to reciprocate in and out of engagement with the under side of the sole and to dwell in said engagement during the time that thc nccdle is cngagcd with the sole, thus holding the sole firmly against the \\'orkguidii ig devices, which will be hcrcinal'tcr described. The lockalog 58 is carried on a lcvcr 59. (See Figs 4, 7, and 8.) This lcvcr .cxtends downward and has its lower end l'orked, as indicated at 59", the fork recciving a fulcrum-pin (30, supported on the base 22. Articulated to the slide 59 is a locking-lever (Si, intcrmcdiatcly lulcrumed on a pedestal 62, rising from the base 20 and extending rearward over the shaft 24. (See Fig. 4.) Said shalt has a cam 63 engaging the lcvcr, and at its rear end the lever is con ncctcd with a rctractilc spring 64, which holds the lever firmly engaged with the cam. 1 In this man ncr the lever (51 is periodically opcrated to raise and lower the slide (30, carrying the lock-dog, moving the lock-dog up in engagementwith the work at the propcr. time and returning the dog i'rom this cngagcincnt. during the l'ccding movement.

Attachcd to the top of the worle-platc at onc'sidc of thc stitch-plate 23 (scc Fig. 3) are the work-guide and threatl-carryingdcvices. 'llic work-guide comprises a plate or), attached to the worleplate 2'2 and lniving an end (36 overhanging the stitch-plate and spaced therefrom so as to permit the sole of the shoe to pass'between said end (i6 and the stitchsp late From said end or extension 66 the work uide is extended upward and thence inwdi 'd to form a hook 67, which has an The lever 52 has a stud l'lO ening 68 therein. (See Fig. 10.) Through tliiis opening the needle 35 is adapted to pass, the hook 66 serving to receive the lower edge of the upper, as Fig. 9 shows. 'By these devices the sole and upper are guided into engagement with the stitch-forming devices and held in the proper position during the At the en opposite the fork 69 the sh e 69 is provided with two indentations 69 and 69 in its inner edge. These indentations are adaptedto engage a roller 71, mounted on .apin 72, which is carried by the plate 65 or work-table 22, as may be desired. At the side opposite the edge having the indentations' 69 and 69 the slide 69 is provided with an indentation 69, which receives a pin *73 rising from the plate 65. By these de-' vices the slide is mounted so that it may reciprocate, and owing to the cavity 69 and 69? and the roller 71 the slide is given a lateral as well as a longitudinal movement. At the end adjacent to the stitch-plate 23 the slide 69 is formed with a horn 7 4, which has an o ening 74 therein adapted to receive the t read. At the base the horn is formed with a In r 74*, also perforated to receive the thread w 'ch is engaged with the horn, as indicated in Figs. 2 and 10. The hornis connected with the body of the thread-carrier by a reduced portion 69, and the horn is ada ted to move back and forth across the path of the needle so as t6 carry the thread into engagement therewith, permitting the loops to be formed reliminary to the forina-- tionof the stitch, best shown in Fig. 9, the reduced part 69"of thethread-carrier passes between the u per and sole, carryingv the threadinside o the shoe. A similar position is taken b the work-holder. The shde-69'is operated y" a lever 74 which en ages in a cavity 69", formed in the slide. aid lever is fulcrumed intermediately on a bracket 75,

dependingfrom the table 22, and extends downward and rearward to a grooved cam 76, attached to the shaft 24, this cam imparting .a vibrating movement to the lever and said lever moving the slideback andforth, as described. 77 indicates va sprin which presses the lever 74 yieldingl to hold it so as to move" the slide 69 am the attached thread-holder into the position shown by broken lines in Fig. 9. 78 indicates a coverplate which is applied to the work-ghiding and thread-carrylng devices to inclose the same.

In constructing shoes or slippers havin felt fabric or other limber material d' icult has been experienced, in holding the felt in' position for stitching. *Inorder to overcome slide 82 an this disadvantage, I providelan attachment ;6

shown in Figs. 13 to 19. vIn 'thiscase' the thread-carrier slide 7 9 is provided,'which is essentially the same as the slide 69, and the slide 79 carrying a horn 80 with an opening therein to receive the thread, as before described. Said slide is formed-With an irregular slot 7 9, which receives a roller 81, thus giving the slide a lateral movement during its reciprocation the same as before described. The slide 79 is provided with desired means. The slide 82. is means of studs 85, risinglfrom a ase-piate 86, the studs fitting wit in the opening or 'cavity 82 in the slide. The slide 82 is provided with a lateral extension 87 at the end overhanging the stitch-plate 22, ,this lateral extension being preferably corrugated and coacting witha jaw 88, carried ona rock shaft 89, suitably mounted on the slide 82. Said rock-shaft 89 is provided with an arm 90, to which is connected any desired means 91 for operating the arm.

The end of the jaw 88 is provided with an o enin 88, serving for the assage of a need e, an below the d its jaws the base-plate 86 is provided witha reduced extension 86, which overhangs the work-plate to form an opening for the reception of the sole, the same as the reduced part 66 in Fig.8. The lever 7'4- imparts to the slide 79 and the thread-carrying cm 80 the same movement described with respect to the slide 69, (shown in F ig. 10,) thus carrying the thread back and forth across the pathof the needle. The slide 82 is reciprocated back and forth laterally of the stitchline over the stitchlate by .the device 84,

and simultaneously t e shaft 89 is rocked so as to engage and disengage the jaws 87 and 88. These jaws open each time that they move-away from the stitch-line or rightward from the position shown in Fig. 19, the-felt upper being inserted between said jaws. When the jaws return into en agement with each other, the felt will be gripped between the jaws, and then the slide 82 andits attachments moved back to the osition shown in Fig, 19, carrying the felt with it and holding the felt securely while it is stitched, the neodle passing u overthe opening 88 in the jaw 88. As t 1e needle descends the slide 82 moves back again and the jaws againmpen taking a fresh hold on the felt upperand again drawing it into position. -It will be the felt upper and draws it back into posit on for sewing each time that a stitch is formed,

This device 84 may be of any desired form and operated by any guided by ICC ' seen that this device intermittentlyienghgesmeans for operating the needlebar, said bar having a groove therein, a cast-oil adapted to these devices constituting a positively-act- -ling means for guiding and holding the felt up er in the proper position.

holder and thread-carrier pass between the, sole and upper, the thread-carrier movmgm the space between said parts thus operating inside of the shoe, andin the lorm shown n Figs. 13 to 19 the same is true ol the aws 87 and 88. In this way the sole and upper are held in the proper position for stitching, and

are guided in their mifi'i'anents through the machine. Upon starting the revolution of the shaft 24 the cams and driving devices actuated thereby are set into motion. The needle descends, passing through the sole and upper, and the tlireadcarrying horn St) or 74, as the case may he; moves the thread into the path of the hook in the necdle,so that upon the descent of the needle a loop is formed and drawn through the work. As the needle Withdraws from the work the loopcr 36 cugages the needle performing its usual lunctions. While the needle was passing up through the work and back to its lower position, the lock-dogs 58 were raised by the. dc-

vices for operating them, thus clamping the sole firmly under the work-guiding extension 66 or 86. Then as the needle descends the iced-dog 47 passes through ihcstitcliplate, engages the work, and advances it into position to receive the next stitch. This operation is carriedon until the upper is entirely stitched to the sole exceiting for a short space at the back of the heel. The upper and sole stitched, in this manner are then slipped out of engagement with the work-holding and thread -carry'ing devices and the unstitched portion of the up )er of theshoe may be secured to the sole or heel by one or two tacks driven in at this point.
